Product Description

The SN74LS257DR is a versatile device that is commonly used in digital data processing systems. It allows for the selection of one of two data inputs for each multiplexer by using a common select input, which makes it ideal for applications such as data routing, signal gating, and multiplexing. The 3-state outputs can interface directly with and drive data lines of bus-organized systems. With a wide operating voltage range and fast switching speed, the SN74LS257DR ensures minimal propagation delay and is suitable for various high-speed logic applications.

Each multiplexer has both true and inverted inputs, providing added flexibility in signal processing. This device is fabricated with Low Power Schottky technology, which provides a reduced power consumption while maintaining high-speed operation. The SN74LS257DR comes in a compact SOIC-16 package, making it ideal for space-constrained applications.

As a product of Texas Instruments, a leader in semiconductor design and manufacturing, the SN74LS257DR is built with the quality and precision that engineers and designers have come to expect from TI products. This device is a reliable choice for those looking to implement efficient data selectors/multiplexers in their digital systems.
